Near our car lot we had mechanics that we were friends with so they gave us good deals when we had problems. In time you will meet people like that because they want your almost guaranteed repeat business. What I would do for my first deal or before the first deal is to go around nearby lots and ask what kind of finance people they use. Then get into contact with a "rep" and they will gladly come to you and walk you threw it. Software is available a popular one is this one http://www.nowcom.com/dealerdesktop.asp I used automanager http://www.automanager.com/demo/. I like the nowcom company because they are the service that westlake and other finance companies use to see if the customers are approved. They use and own the site https://www.dealercenter.net to see the approvals instantly.

What kind of people will you be financing? Bad credit, good credit?
